Ordering example:
The cable is 15kV, 3-core 95mm² copper conductor with core insulation diameter of 22mm. Order WEBKIII 15/630D05C3.
Note:
Sealing or solderless grounding kits shall be ordered separately.
Insulated plug with capacitive test point is available upon request.
Please add "-X" for cable with copper wire shield without armour, like WEBKIII 15/630D05C3-X.

Note: * refer to the condition when installed on an appropriate equipment bushing.
Compact design, 100 mm to another connector, suitable for small bushings.
No earthing wire, insulation is achieved by rubber and air.
This separable rear connector is made of premium EPDM that has excellent electrical properties and outstanding mechanical strength. It also features high resistance to tear, ozone gas, oxidation and corrosion.
This bolted rear connector works with good thermal stability and delivers thermodynamic performance. Its marvelous sealing performance allows for underwater operation.
